Question

我正在使用xcode在C中完成学校项目。任务是创建一个命令行应用程序，用于检查单词在文本文件中出现的次数和次数。到目前为止，我刚刚创建了代码的第一步，我已经将第一个争论论点设置为＆＃34; hej＆＃34;即使我还没有使用这个词，并且由于没有输入第一个文件名因此为NULL，我已将其设置为名为＆＃34; hej.txt＆＃34;的现有文件，以便将我的代码测试为我去。

这一点之前有用：

#include "stdio.h"
#include "string.h"


struct fileSearch
{
    char *inFile;
    char *outFile;
    char *searchWord;
};

int main(int argc, char *argv[])
{

    int index = 0;
    struct fileSearch f;
    f.searchWord = argv[1];
    FILE *searchFile;

    //For-loop to assign filenames
    for(index = 0; index < argc ; ++index)
    {
        if((strcmp(argv[index], "-i") == 0) && argv[index] != NULL && strcmp(argv[index + 1], "-o") != 0)
        {
            f.inFile = argv[index + 1];
        }
        if((strcmp(argv[index], "-o") == 0) && argv[index] != NULL && strcmp(argv[index + 1], "-c") != 0)
        {
            f.outFile = argv[index + 1];
        }
    }

    if (f.searchWord == NULL)
    {
        printf("You didnt enter a search word");
    }

    if (f.inFile == NULL)
    {
        f.inFile = "hej.txt";
    }


    if (f.outFile == NULL)
    {
        f.outFile = "stdout.txt";
    }

    printf("%s & %s & %s", f.searchWord, f.inFile, f.outFile);
    return 0;
}

然后打印出搜索词，输入文件名和输出文件名。

然后我添加了代码的下一步，它将打开文本文件＆＃34; hej.txt＆＃34;然后读取字符串并打印出来。

#include "stdio.h"
#include "string.h"


struct fileSearch
{
    char *inFile;
    char *outFile;
    char *searchWord;
};

int main(int argc, char *argv[])
{

    int index = 0;
    struct fileSearch f;
    f.searchWord = argv[1];
    FILE *searchFile;

    //For-loop to assign filenames
    for(index = 0; index < argc ; ++index)
    {
        if((strcmp(argv[index], "-i") == 0) && argv[index] != NULL && strcmp(argv[index + 1], "-o") != 0)
        {
            f.inFile = argv[index + 1];
        }
        if((strcmp(argv[index], "-o") == 0) && argv[index] != NULL && strcmp(argv[index + 1], "-c") != 0)
        {
            f.outFile = argv[index + 1];
        }
    }

    if (f.searchWord == NULL)
    {
        printf("You didnt enter a search word");
    }

    if (f.inFile == NULL)
    {
        f.inFile = "hej.txt";
    }


    if (f.outFile == NULL)
    {
        f.outFile = "stdout.txt";
    }

    printf("%s & %s & %s", f.searchWord, f.inFile, f.outFile);

    //Open file and read
    char str[60];

    searchFile = fopen(f.inFile, "r");
    if(searchFile = fopen(f.inFile, "r") == NULL)
    {
        printf("Error: There is no file with that name.");
        return -1;
    }

    if(searchFile == NULL)
    {
        printf("The file is empty");
        return -1;
    }

    while(fgets(str, 60, searchFile) != NULL)
    {
        puts(str);
    }

    fclose(searchFile);

    return 0;
}

但是现在它成功构建了代码但是当我尝试运行它时，我收到此错误消息：

＆＃34;错误：可执行文件不存在：＆＃39; / Users / Slattegard / Library / Developer / Xcode / DerivedData / Coursework-chwsqczjjgxcyegnxgysiaigslvq / Build / Products / Debug / Coursework＆＃39; 错误：无法启动＆＃39; / Users / Slattegard / Library / Developer / Xcode / DerivedData / Coursework-chwsqczjjgxcyegnxgysiaigslvq / Build / Products / Debug / Coursework＆＃39;＆＃34;

并且问题导航器给了我这条消息：

＆＃34;检查依赖项警告：没有处理文件的规则＆＃39; /Users/Slattegard/Documents/Coursework/Coursework/Find.c'类型为sourcecode.c，用于体系结构x86_64＆＃34;

任何人都知道我哪里出错了？

Xcode（C）＆＃34;检查依赖关系＆＃34;和＆＃34;错误：可执行文件不存在＆＃34;
